ProPresenter to ATEM (black part of Lowerthird is keyed out)

[Femi Adesoji]

How do I stop ATEM from keying out the black part of my lower third, I’ve tried adjusting the gain on the luma key tab and cropping which affects other graphics.

thanks

A luma key, by definition, uses the black and non-black parts of your image (aka the luminance) to determine what to key out. Anything that is black is removed.

Instead, try using a chroma key to select a different color to key out, like blue or green, and setting that as your Screen Color in ProPresenter’s Display preferences.

Alternatively, you will need to purchase either a UltraStudio or Decklink output device and use ProPresenter’s Alpha Key module instead.
